A Comparison of CP-OFDM, PCC-OFDM and UFMC for 5G Uplink Communications [PDF]
IEEE Access, 2018 Polynomial-cancellation-coded orthogonal frequency division multiplexing (PCC-OFDM) is a form of OFDM that has waveforms which are very well localized in both the time and frequency domains and so it is ideally suited for use in the 5G network.

PCC Net: Perspective Crowd Counting via Spatial Convolutional Network [PDF]
IEEE transactions on circuits and systems for video technology (Print), 2019 Crowd counting from a single image is a challenging task due to high appearance similarity, perspective changes, and severe congestion. Many methods only focus on the local appearance features and they cannot handle the aforementioned challenges.
